[p2-dev] error while loading a remote repository using IMetadataReposito

[Dileepa Jayakody <dileepa@xxxxxxxx>]

Hi Devs,

We are using equinox p2 version:3.7 as the provisioning platform for our osgi based product. 
I have an issue with org.eclipse.equinox.p2.repository.metadata.IMetadataRepositoryManager when I try to load a p2 repository from a remote URI.
The code works fine with local repos but throws a null-pointer @metadataRepositoryManager.loadRepository(location, new NullProgressMonitor()); when trying to load a remote repository.
It seems p2 cannot load an indexFile from the given remote repo URI.
I tested this with a sample p2 repo both as a local repo and a hosted remote repo. It works fine with the local repo but fails when it's given as a hosted remote repo :(
 
Can you guys give me a hint what could be going wrong here?
Any help on this matter is much appreciated.

Following is the stack-trace;

java.lang.NullPointerException
